Microsoft's idea of system administration...
... is that everything has a desktop. So obviously, if you are running an Ubuntu virtual machine you need XRDP to administer it.
I thought with Powershell they might have gotten over this mentality, but it seems not.
Anyone sane running services in Ubuntu VMs will be running Ubuntu *Server* edition which cuts out the desktop. They'll administer them over ssh, and they'll use bulk administration tools like ansible, stackstorm, salt, chef, puppet etc.
They might revert to the console if they screw up the network interface configuration, but that's about it. VGA text or serial console is fine for that.
